Johan Hovold ccb7cd3218 mfd: altera-sysmgr: Fix device leak on sysmgr regmap lookup
Make sure to drop the reference taken to the sysmgr platform device when
retrieving its driver data.

Note that holding a reference to a device does not prevent its driver
data from going away.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
